+## Release Process (for maintainers)
+
+The [`release`](https://github.com/drivendataorg/deon/blob/master/.github/workflows/release.yml) GitHub Actions workflow automates the process of releasing a new version of `deon`.
+
+All you need to do kick off the release process is to update the [`VERSION`](https://github.com/drivendataorg/deon/blob/master/VERSION) file and merge the change into the `master` branch. The `release` workflow watches the master branch for changes to this file.
